Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

A new research paper reframes the simulation hypothesis, asking whether reality could be simulated and what science can test.

Researchers say it's impossible to use algorithmic computation to generate everything in our universe. The possibility that our entire universe merely exists inside a computer simulation is more than ...

A military planner at the Joint Forces Command in Norfolk, Virginia, watches a battle unfold without taking his eyes off the computer screen. The software is tracking a million vehicles spread over ...

The simulated universe theory implies that our universe, with all its galaxies, planets and life forms, is a meticulously programmed computer simulation. In this scenario, the physical laws governing ...

In 1952, at Los Alamos Scientific Laboratory, theoretical physicists Enrico Fermi, John Pasta and Stanislaw Ulam brainstormed ways to use the MANIAC, one of the world’s first supercomputers, to solve ...

Elon Musk and others find it plausible that our experiences result from events in a computer simulation, just like the characters in the Matrix movies. An alternative view, supported by both common ...

If such a simulation were possible, the simulated universe could itself give rise to life, which in turn might create its own simulation. This recursive possibility makes it seem highly unlikely that ...

Physicists have long struggled to explain why the universe started out with conditions suitable for life to evolve. Why do the physical laws and constants take the very specific values that allow ...

FORT INDIANTOWN GAP, Pa. — For the past few years, the U.S. Army has transitioned training priorities to focus on large-scale combat operations against what is known as near-peer advisories, a ...
